The build on which i were stuck was a fey related warlock and i was trying to get into this class , not because were strong or anything (for a warlock isn't too strong) but because was original , the Courtier from the Fey feature. My main problem was that leadership, and because without that would have been similar ( i could use each fey heritage feat but other than that i didn't know), for the race i was thinking at a duskling so that i could use essentia from the start , so that could have been good later. But i didn't found a way to gain leadership so i was stuck
